MACHINE FOR TURNING, BORING,1&o.

T Specification of Letters Patent No. 7,977, dated March 11 1851.

To all whom it may coneem Be it knownthatwe, MARTIN WAY and THOMAS R.WAY, of Paintersville, int-he county of Greenland State of Ohio, haveinyented a newandwuseful Machine for Bendln'g, Drilllng Borlng,andfTurning Wood had to the accompanying drawing, which forms partwhich-- r a r r yFigurejl represents a view in perspective ofourimprovedmachine. Fig. 2 is a front elevation of the same, and Fig. 3 isa transverse section at thelinew m ofFig. 1. r r

Ourniachine is constructed tobend metals to curves'of any requiredradius, and tobore,

drill, and turn bothwood and metals.

It is particularly applicable to the business of carriage-making as itembodies in a single machine the means of effecting many of thosemechanical. operations which are re quired in constructingwheelcarriages, and which have heretofore been effected in separatemachines. r l n i The various moving portions ofour machine are mountedupon twostrong frames or bedsA, B, which cross each other at rightanglesin theform of'a T and are firmly bolted togethen The upperedges ofthe side pieces of each frame are A shaped to support and guide thevarious carriages which are required for different kinds of work. Astandard G sliding vertically in dove-tailed grooves is fitted to thefront of the machine at its middle, and a corresponding shorter slidingstandard c is fitted to the oppositeside piece of thebed These standardsareeach raised and depressed in an equal degreeby means of a screw (4which turns in a lug projected from the side piece of the bed, and whosethreads engage in a female screw cut in a lug b projectedfrom thestandard above it. The head of each screw is fitted with a pinion c, thetwo being of equal size and both gearing into an intermediate wheel cl,so that whenfione screw is turned to raise or depress one standard theother screw is turned with equal velocity to move the other standardequally in thesame direction. Thescrew a at the front of the machine isfitted with a hand wheel 6 by means of which it may be turned withfacility and a scale D is secured to the side piece of the machine toshow the distance to ofthis specification and in which the standards areto be raisediii bend? ing metals of various thicknesses. The standardsG, C,support aroller E which crosses the bed A, its gudgeons beingsupported in boxes inthe standards. Thegudgeons at each end of theroller are prolonged beyond the standards. The prolonged ex} tremit-y atthe front of the machineis fitted i ;with a cog wheel F and with apiniong.

The cog-wheel gears intoqa pinion f whose shaftis supported by thestandard C and is Two carriages J J are mo-untedupon the A shaped edgesof the bed A. These each'supi port a roller E and are moved in. an squatdegree to and from the ceiiterroller E by means of a rightand left screwj which acts upon nuts fixed to each carriage. 1 The head of this screwis. fitted with a hand wheel by means of whichit can be turned withfacility to set the rollers E at any desired distance from the middleroller E. A scale K] is at tached to one of the sidepieces of the bed bymeans of which the curvature or any piece of metal which isbent bypassing it under the centerroller andoveithe two lateral ones, is shownby the position of the carriage with respect tothe divisions of thescale. p r a A movable headstock I is mounted upon a saddle L whieh: issecured by means of clamp screw 70 to a carriage Mwhich lscon structedtoslide to and fro uponthe A'edges of the side pieces ofthebed BLAninten mediate sliding carriage N is also con st-ructed to slide uponthis bed and is moved to and fro by means of a pair of feed screws m, m,which act upon a pair of nuts a, a, secured to the opposlte sides of thecarnage.

These screws are prevented from moving endwise'by collars o, andtheirheads are fitted with aspair of equal cog-wheels P P whose {teeth engagewith those of the pinion g on the roller E. This sliding carriagesupports a pair of tool holdersRRwhich are also used to clamp any pieceof wood or metal which is to be drilled or bored. The tool:

holdersheach consist of an upright frame with two sliding blocks 79 pwhich are moved up and down at will by screws r-r. They are made fastbya crossbar O and clamp screw 9 to a disk S which turns upon a lower diskS; the latter is constructed to slide transversely upon shaped guides tt; the tool holders are also constructed to slide toward or from eachother on guides 8 secured to the upper disk S; and the arrangement ofthe various moving parts thus described is such that the clamp-screw qnot only secures the tool holders R R to the disk S on which they stand,but also secures this disk to the lower one and makes fast the latter tothe carriage. The lower disk with the various devices mounted upon it ismoved to and fro on the carriage by means of a screw u to whose head ahand wheel is fitted. An adjustable scale T is fitted to one of the sidepieces of the bed, by means of which the distance to which the carriageN is moved, is shown.

When the machine is used for turning, a face plate U or a chuck isfitted to the shaft H of the stationary head stock; when used for boringa boring bar is inserted between the stationary and movable head-stocks;when the drilling is to be done the drills are fitted to a socket in theend of the mandril.

When iron, such as wheel tire for example is to be bent with thismachine, the carriages J J are moved by the screw j to such a distancefrom the center roller as is shown by the scale K to be the proper onefor giving the required cuvature to the tire, the center roller is thenraised by raising the standards by means of their screws or at until thebar can be passed over the side rollers and beneath the center roller E,which is then depressed upon the bar by the action of the screws a andis turned by applying the hand to the crank Gr. The turning of theroller, whose barrel is roughened, carries the iron to and fro betweentheunder side of the upper roller and the upper sides of the lat-- eralroller. As the bar is bent, the central roller is gradually depresseduntil it arrives at the lowest position required to give the bar theproper curve; this lowest position varies with the thickness of the barand is shown for each thickness vof iron by the scale D.

dril and be bored by a stationary drill se cured to the tool holder andadvanced against the article.

If a hub is to be bored to receive the boxes, it is clamped between thetool holders and is fed by the action of the feed screws m against aboring bit secured to a boring bar inserted through the hub between themovable and stationary head-stocks; the boring bar is driven by a pin '0in the face plate V, and the distance to which the bit enters the woodis shown at any moment by the scale T.

When the machine is used for turning, the tools are secured in the toolholders R R, which may be'placed in any required position to suit thework.

hat we claim in the foregoing as our invention and desire to secure byLetters Patent is- I The tool and block holder herein describedconsisting of two upright frames capable of movement toward each otherand of being clamped at a greater or less distance apart as may berequired to adapt them to holding blocks of different sizes and tools ofdifferent lengths or forms, each frame being provided with uprightparallel guides carrying adjustable jaws for holding boring or turningtools at different heights and angles and to aid in holding blocks ofirregular forms; these frames being mounted upon a carriage capable ofbeing turned or moved right or left so as to hold the tool or presentthe substance to be bored in the required position, substantially asherein set forth.

In testimony whereof we have hereunto subscribed our names.
